ABSTRACT:Chikungunya is an infection caused by the chikungunya virus (CHIKV). The virus is spread between people by two types of mosquitos. Aedes albopictus and Aedes aegypti. They mainly bite during the day. CHIKV likely originated in Central/East Africa, where the virus has been found to circulate in a sylvatic cycle between forest-dwelling Aedes species mosquitoes and nonhuman primates. The incubation period of the chikungunya virus ranges from one to twelve days, and is most typically three to seven. The disease may be asymptomatic, but generally is not, as 72% to 97% of those infected will develop symptoms.
